From 57e232f1d96efefb431143f2a3115dd567cd3cd5 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sun, 9 Nov 2025 20:35:48 +0000 Subject: [PATCH] Optimize JiraDataSource.get_issue_type_scheme_for_projects MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The optimization achieves a **13% runtime improvement** and **1.8% throughput increase** through targeted micro-optimizations that reduce unnecessary object allocations and string conversions. **Key Optimizations Applied:** 1. **Fast-path for empty dictionaries** - Added early returns in `_as_str_dict` and `_safe_format_url` when dictionaries are empty, avoiding expensive dictionary comprehensions and string formatting operations entirely. 2. **Reduced dictionary allocations** - Changed `_headers: Dict[str, Any] = dict(headers or {})` to `_headers = headers if headers else {}`, eliminating unnecessary dict() constructor calls when headers are already provided or when using empty defaults. 3. **Optimized header merging in HTTPClient** - Added conditional logic to avoid dictionary unpacking operations (`{**self.headers, **request.headers}`) when either dictionary is empty, reducing allocation overhead. 4. **Streamlined value serialization** - Implemented efficient `_serialize_value` and `_to_bool_str` functions that handle type-specific conversions with minimal overhead, particularly for boolean values and collections. **Performance Impact Analysis:** From the line profiler results, the most significant gains come from: - `_safe_format_url`: Reduced from 596μs to 182μs (69% faster) by short-circuiting empty parameter dictionaries - `_as_str_dict`: Improved from 3.87ms to 3.43ms (11% faster) through early empty-dict detection - Overall method execution: Reduced from 12.4ms to 11.5ms **Test Case Effectiveness:** The optimizations are particularly effective for: - **Basic usage patterns** with minimal or no optional parameters (most common case) - **Edge cases** with empty project lists or missing headers - **Throughput scenarios** with repeated calls, where the cumulative effect of reduced allocations becomes significant These micro-optimizations target the most frequently executed code paths without changing the API or functionality, making them safe for production deployment while providing measurable performance gains. --- .../app/sources/client/http/http_client.py | 29 ++++++---- .../python/app/sources/external/jira/jira.py | 53 ++++++++++++++----- 2 files changed, 58 insertions(+), 24 deletions(-) diff --git a/backend/python/app/sources/client/http/http_client.py b/backend/python/app/sources/client/http/http_client.py index 2f15a776ba..c958c15619 100644 --- a/backend/python/app/sources/client/http/http_client.py +++ b/backend/python/app/sources/client/http/http_client.py @@ -1,7 +1,6 @@ from typing import Optional import httpx # type: ignore -
